摘要: The detection and monitoring of mass movement susceptible slopes plays a key role in mitigating hazards potential damage associated with creeping landslides. In this paper, we use observations from both Interferometric Synthetic Aperture Radar (InSAR) Global Positioning System (GPS) to assess the slope stability Sarcheshmeh ancient landslide North Khorasan province northeast Iran. InSAR were obtained by time-series analysis Envisat SAR images covering 2004-2006, whereas repeated GPS conducted campaign measurements during 2010-2012. Surface displacement maps are indicative stability. Hydrogeological suggests that multi-year drought lower than average precipitation levels over last decade might have contributed current dormancy landslide.
